Netptune has 8 named moons (4 unnamed) and has large storms with the fastest winds of any planet in the solar system (2000 km/hr.).
The unit of frequency is the hertz (Hz), one cycle per second, named after Heinrich Hertz. For our purposes, we shall use much higher frequencies. One thousand Hz is a kHz (kilohertz); one thousand kHz is a MHz (megahertz); one thousand MHz is a GHz (gigahertz); one thousand GHz is a THz (terahertz).
So 1 kilohertz = 10 3. The definition of a hertz is as follows: The hertz (symbol Hz) is the SI unit of frequency. It is named in honour of the German physicist Heinrich Rudolf Hertz who made some important contributions to science in the field of electromagnetism.
